This is an old thread, the OP hasn't logged into the board for over a year, and never provided a followup.

your Fiero swap options

Both have been done as you know. Of the guys I know with swaps I can tell you this. Northstars have been put in and pulled out due to problems on more than 2 occasions.
SBC's once done are normally rock solid, but more expensive to swap in due to all the bits and pieces required.
The fastest, bar none, is PBJ's 10 second 3800 turbo'd GT. He also had the fastest 4.9 turbo'd.

I am doing a 4.9 carb'd because I want some power and simplicity. It won't be the fastest, but it will still go well, and will be trouble free.

Hope this helps.

What I was suggesting was buying one that was done so you have a known good setup to move to your project car.

you know what this thread is missing? Pictures!!

Not really wanting one already done. I really enjoy building them myself. I have a Pontiac G6 6 speed I plan to put in it. Just still undecided on the engine. My two concerns is not wanting to get more than the car can handle with a V8 and then I'm just not sure how well that 3800 is gonna do once I get larger wheels on it. I mean I see these Fieros doing well with the 3800 but most of what I've seen has been like on 14s and 15s but what about on larger wheels like maybe 18s. It's a lot to consider.

Yea I'm kind of the same. I'm really sold on V8s. I have no intention of running it on track just curious to what some of the V8 Fieros were running. Don't want to end up building more motor than the car will handle. Ive built 350s in the past so pretty confident in those engines.

I've never had a car on the drag strip. Fiero or otherwise. Drag racing is fun to watch, but it just isn't what makes my own cars fun or not fun to own for me. each to his (or her) own I recon.
whyholdback is typical of the realfierotech crowd in his passion for the sc v-6, and that's fine, but they just aren't my cup of tea. if his 6 beats (any) v-8 at the drag strip I say "yippie, great race", but I'll still own the V-8.
Your milage may vary,

TH trans isn't up to the task for most drivers. the Getrag 5 speed is nice, but getting harder to find a good one. The 4 speed from a v-6 Fiero (stronger case that the 84 4 banger) is my preference. 4th is an OD in the 4 speed, and I've found them to be very strong.

or you could just buy one of mine, as they sit in the garage mostly, since I discovered street rods.

Supercharged 3800 Series 2, 4T60E, low 10s. No transverse V8 Fiero on earth has ever proven itself quicker.
And if y'all had bothered to do ANY searching on fiero.nl, you would know this.

The 5.3 from an Impala or similar will fit just like the Northstar.
Northstars have serious head gasket problems. The head bolts break and are VERY expensive and difficult to repair. A head gasket will cost you as much as the 5.3 engine!!!. Been there, done that.

against all odds

The northstar is good(based on personal experience). BTW, it's being discontinued either this year or next yr---notice how cadillac doesn't use v-8's anymore? Except in the suv's which are LS'es.

But the small block will be much easier/cheaper/faster to get running. So, i personally, would go small block. Incidentally, recently i've been thinking about doing a lambo conversion---to try to make a profit on.

The other question is how much power can the TH-125 transaxle handle?
